Claims (11)
- レーザ式車両用前照灯(2)が、少なくとも1つのレーザ光源(3)と、前記レーザ光源(3)が照射でき、したがって励起されて可視光を放射できる少なくとも1つの発光素子(4)とを備え、前記導光素子(1)を実質的に前記レーザ光源(3)と前記発光素子(4)の間に配置することができ、前記導光素子(1)が光入射面(5)と光出射面(6)とを備えることを特徴とし、前記光入射面(5)の入射断面積が前記光出射面(6)の出射断面積よりも広く、前記光入射面(5)と前記光出射面(6)を接続する内面(7)を介して、前記光入射面(5)を通って放射される光を前記光出射面(6)の方向に集束させることができる、レーザ式車両用前照灯(2)向けの導光素子(1)。
- 前記導光素子(1)の受光角(300)が、前記導光素子(1)の光軸(100)に対して0°〜45°の間であることを特徴とする、請求項1に記載の導光素子(1)。
- 前記導光素子(1)の前記内面(7)が、実質的に放物面または自由曲面として形成されることを特徴とする、請求項1または2に記載の導光素子(1)。
- 前記導光素子(1)の外面には、前記光入射面(5)と前記光出射面(6)の間の領域において、光が透過せずかつ/または反射する被覆(8)が、少なくとも各領域に、ただしとりわけ完全に設けられることを特徴とする、請求項1〜3のうちいずれか一項に記載の導光素子(1)。
- 前記発光素子(4)用の少なくとも1つのレセプタクルが前記光出射面(6)の領域に設けられ、前記レセプタクルが、特にブラインド・ボア(9)、または前記導光素子(1)によって完全に囲繞された空洞(10)として形成されることを特徴とする、請求項1〜4のうちいずれか一項に記載の導光素子(1)。
- 前記光出射面(6)が、光が透過しない境界画定要素(15)によって少なくとも部分的に覆われることを特徴とする、請求項1〜5のうちいずれか一項に記載の導光素子(1)。
- 少なくとも1つの反射器要素(11)が、導光素子(1)の周りに延在し、前記光入射面(5)と前記光出射面(6)の間、好ましくは前記光出射面(6)の前記領域に設けられて、前記発光素子(4)から放射される光を、前記光入射面(5)から離れる方向に偏向させることを特徴とする、請求項1〜6のうちいずれか一項に記載の導光素子(1)。
- 少なくとも1つのレーザ光源(3)と、前記レーザ光源(3)が照射でき、したがって励起されて可視光を放射できる少なくとも1つの発光素子(4)とを備え、請求項1〜7のうちいずれか一項に記載の少なくとも1つの導光素子(1)が、前記レーザ光源(3)と前記発光素子(4)の間に配置されることを特徴とする、車両用前照灯(2)。
- 前記レーザ光源(3)は、前記レーザ光源(3)の光が前記車両用前照灯(2)の主放射方向(200)」に対して放射されるように、車両用前照灯(2)の前記主放射方向(200)で見て、前記発光素子(4)の前方に配置されることを特徴とする、請求項8に記載の車両用前照灯(2)。
- 少なくとも1つの遮蔽物要素(21)が設けられ、これにより、前記導光素子(1)の光入射面(5)によって反射される光、または前記車両用前照灯(2)の前記主放射方向(200)での前記導光素子(1)の内部からの光を遮蔽することができることを特徴とする、請求項8または9に記載の車両用前照灯(2)。
- 前記遮蔽物要素(21)が、前記レーザ光源(3)と前記導光素子(1)の間に延在する接続部品として形成され、特に管状または半管状に形成されることを特徴とする、請求項10に記載の車両用前照灯(2)。
